CULTIVATOR AND HARROW.

SPECIFICATION forming part of Letters Patent No. 331,589, dated December 1, 1885.

Application filed August "i, 1885.

To all whom it may concern:

Be it known that I, DALTON WALLS, of Appleton City, in the county of St. Clair and State of Missouri, have invented certain new and useful Improvements in Cultivators and Harrows, of which the following is a full, clear, and exact description;

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figurel is a plan View of one of myim proved machines. Fig. 2 is a rear elevation of the same. Fig. 3 is a sectional side elevation of the same, taken through the line 00 00, Fig. 1. Fig. 4-. is a side elevation of the rear part of one of the beams, and a sectional side elevation of a harrow, taken through the line :1; 3 Fig. 5. Fig. 5 is a plan view of one of the harrows, its shank being shown in section taken through the line 2 2, Fig. 4:. p

The object of this invention is to provide cultivators and harrows constructed in such a manner that they can be readily guided and controlled by plowmen riding upon them or walking in their rear, and can be readily adjusted for use as cultivators or harrows, as may be required.

The invention consists in the construction and combination of various parts of the machine, as will be hereinafter fully described and then claimed.

A are the wheels, the axle B of which, at the inner sides of the said wheels, is bent into crank-form, as shown in Figs. 2 and 3, to obtain space beneath the said axle for the free movement of the plow-beams O. The forward ends of the beams O are hinged to and between the ends of clevises D or other couplings, so that the rear parts of the said beams can have a free lateral movement. The clevises D are passed around and hinged to the rod E, so that the rear ends of the beams G can have a free vertical movement. The parts of the couplings D that pass around the rod E are made wide to give them a wide bearing on the said rod, and thus prevent the plows from rocking lat- V erally. The end parts of the rod E are bent to the rearward at right angles, and their ends are rigidly attached to the axle B, at or near its lower angles, so that the plane of the axle Serial No. 173,829. (No model.)

B and the plane of the rod E will be at right angles with each other. The rear parts of the beams O are bent downward and forward to bring them into proper position to receive the plows F. The rear ends of the beams C have slots G formed in them by bending the said ends into U shape, as shown in Fig. 2, or by other suitable means to receive the bolts B, that secure the plows F to the said beams, so that the said plows can be adjusted higher or lower by loosening the said bolts.

The plow-beams C are made of different lengths, as shown in Figs. 1 and 3, so that the soil thrown by one plow will not interfere with the soil thrown by another plow. The plowbeams O, at or a little in front of the bends of the shorter beams and at each side of the center of the machine, are loosely connected with a cross-bar, I, by staples, clips, or other suitable means, so that each section of plows will move together. Each section of plows can be guided by ahandle, J, the forward end of which is connected with the rod E by a clevis, K, or other coupling, and its rear part is connected with the cross-bar I by a V-shaped brace, L. With this construction the plow-beams O and the handle J of each section will always be parallel with each other, and will be free to move laterally and vertically, so that the plows can be guided by means of the handles J.

To the center of the rod E is attached the rear end of the tongue M, to which the draft is applied, and which is strengthened in position by the bar N. The forward end of the bar N is attached to the rear end of the tongue M, and its rear end is attached to the center of the axle B. The bar N also strengthens the connection between the rod E and the axle B.

To the rearwardly-projecting end 0 of the bar N, or to a spring-bar, 0, attached to the said bar and to the axle B, is secured the drivers seat 1?, so that the machine can be used as a walking-cultivator or as a ridingcultivator, as may be desired.

To the handles J, in front of the cross-bars I, are attached loops or stirrups Q, to receive the drivers feet, so that the driver when using the machine as a riding-cultivator can guide the plows with his feet.

To the handles J are attached the ends of short chains R, the upper ends of which are attached to the lower ends of short bars S, placed in dovetailed grooves in collars T, placed upon the axle B, and secured in place by set-screws U. The set-screws U also secure the bars S to the collars T, and pass through slots in the said bars S, so that by loosening the said set-screws the bars S can be adjusted to allow the plows F to enter the ground to any desired depth.

To the collars T or to the axle B are pivoted levers V, the forward ends of .which are connected with the handles J by short chains W, and their rear ends project into such a position that they can be readily reached and operated by the driver with his feet.

If desired, all or part of the cultivator-plows F can be detached and replaced by small V- shaped harrow-frames X,the shanks Y of which incline upward into such positions that they can be readily bolted to the slotted rear ends of the beams O.

The harrow-frames X are each provided with three teeth, Z, as indicated in'Fig. 5.

Having thus described rnyinvention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the axle B, bent upward into U shape and having the cranks on its ends for the wheels A, of the forwardly-pro- 30 jecting U-shaped bar E, secured at its ends to the cranks of the axle, the gang of cultivatorbeains hinged to the bar E, the tongue ll", secured to the bar E, the brace N, connected to the tongue at its lower end and extending upward and rearward to the axle B, and secured thereto, and a spring, 0, secured to or formed on the bar N, and projecting behind the axle, and the drivers seat P, secured to the free end of the spring 0, substantially as set forth.

2. The combination,with the U-shaped axle B, the bar E, at right angles thereto, and the beams O, hinged to the bar E and projecting rearward under the axle B, of the collars T, secured to the axle, and having dovetail grooves, the slotted bars S, working in said grooves, the set-screws U, passed through the slotted plates and collars, and the chains R, connecting the plates S and the beams, substantially'as set forth.

3. The combination,with a cultivator dragbar, of the flat V-shaped barrow-tooth frame X, having the shank Y bent up from between its ends, and the teeth Z on the lower face of the frame, substantially as set forth.
